All flags of the world. Country, national flags

True. The national flag of Spain, often associated with the tradition of bullfighting, carries significant symbolism. The important yellow represents the warm, sunlit arena—often resembling the sandy ground where bulls are fought. The deep red represents the blood that is historically shed during these dramatic circumstances. All we know the interesting fact that bulls themselves are colorblind to red; they do not "smell" the color as a threat or irritant, contrary to popular belief. This highlights the intriguing relationship between the visual elements of bullfighting and the biology of the bulls involved.

The shape of the Swiss flag is square, and there are two flags of this kind in the world. However, this depends on some factors. Only in sports and at sea should the Swiss flag be rectangular. Although Switzerland is landlocked, it can also have a merchant navy in international waters. Moreover, a special rule must be applied if the navy sails on the ocean under the Swiss flag. During World War II, a unique "Swiss flag at sea" was introduced with an aspect ratio of 2:3, the shape of which corresponded to the usual rectangular flags for naval forces. A rectangular version of the Swiss flag can also be seen at the Olympic Games. One of the most interesting facts about Switzerland is that the white Swiss cross on the country's flag was adopted as a field sign during the wars between the Swiss cantons, and then it was adopted as a national flag.
